Welcome

This website shows real-time data from monitoring programs in Lake Champlain and throughout the Lake Champlain Basin.

Please choose a data type above. All data plots are interactive. Hover over plots to see details on each measurement, or click and drag to zoom in on a section. Additional features can be found at the top right of each plot.

This website is under development. All data is provisional and for educational purposes only.

Info

Lake level, lake temperature, and tributary discharge data is collected by the US Geological Survey.

The Lamoille River and Malletts Bay buoys are part of a pilot study to upgrade and modernize the Lake Champlain Long-term Monitoring Program. These buoy are instrumented with an array of water quality and weather sensors that measure several parameters every 15 minutes.

Lake Champlain monitoring buoys are supported by the Lake Champlain Basin Program, in partnership with New York and Vermont Departments of Environmental Conservation and SUNY Plattsburgh.

Snow data provided by NWS Burlington office and the University of Vermont. Latest and historical Mt. Mansfield snow depth data is available in comma-separated format at this link.
